(246−152, 246, 801)-Net in Base 4 — Upper bound on s

There is no (94, 246, 802)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13441 220904 524504 603743 120182 357302 266735 477098 539381 218006 290483 494072 067851 333676 331774 404228 598668 365134 574531 210095 251254 514722 974346 357393 218720 > 4²⁴⁶ [i]
